Abstract

We investigate domain patterns in a ferromagnetic thin film under an oscillating field. Using a simple two-dimensional Ising-like model, we simulate various kinds of domain patterns and discuss the mechanism of the appearance of those patterns. The simulations of several kinds of lattice patterns shows that the type of a lattice (e.g., square or hexagonal) depends on the amplitude and frequency of the field. Under some conditions, we observe traveling stripe patterns that moves very slowly compared with the frequency of the field. In the case of a high-frequency field, a concentric-ring pattern can appear around a strong defect. Those patterns are explained theoretically by two different methods.
